Except WoW expansions come out every 2-3 years not every 4 months and have enough content to last that long. Also destiny is barely an mmo. The dark below came out two weeks after an iron banner meaning you could grind to rank 5, spend 17.5k on a gun and have it be "permanently" outclassed by a vendor weapon in 14 days. And here we are yet again. Bungie can't say with one face that we build our legend and carve our own path and say with the other that we have to trash everything and start over every 4 months.
